"When the presence of a police member in a community becomes such a problem that traditional owners are writing letters condemning the behaviour… that should absolutely be something of concern," she said.

She demanded to know why the officer had been allowed to keep his position following a letter from traditional owner Boniface Perdjert on behalf of the Kardu Diminin Corporation "formally notifying the Government of the sergeant's lack of care about the lives of Aboriginal people, failure to work well with Aboriginal people, rough treatment of Aboriginal people, and failure to work with traditional owners and the inability to listen or to understand the community in which he works".

Ms Gunner said how the matter would be handled was an issue for Police Commissioner Reece Kershaw.

"That officer is afforded natural justice and procedural fairness and it can take a bit of time but there are reasons for that," Mr Kershaw said.

"I can assure you that we have taken the matter seriously and it is still an ongoing issue for us."

He said the officer would remain in place in the community until the investigation was completed.

No response from NT Police Commissioner

The previous General Orders on the Use of Force set out the justifications for when police could deploy their weapons.

Regarding firearms, the now-defunct 2012 document stated that officers were only allowed to use their gun to "protect human life" and to "lawfully destroy animals".

Regarding batons and other weapons, the use of weapons had to be "a reasonable response in the circumstances and not an unnecessary use of force".

The police spokesperson told the ABC that NT Police wanted to do away with "prescriptive content" when it came to general orders and corporate policies, and that the concealment of the document was a result of "a project to streamline and rationalise police General Orders".

The ABC made three requests to interview Northern Territory Police Commissioner Reece Kershaw and did not receive a response.

The ABC also requested an interview with new Police Minister Nicole Manison, but was told: "General Orders are a matter for NT Police".
